An atmosphere is the sphere of gasses (like oxygen)held by a planet's gravity.
nitrogen
Really high! It is very big!
In mine, it's nitrogen. How about yours ?
Good ozone is formed there. It protects us from UV rays of the sun.
Assorted gases such as argon, the rest of the atmosphere is pretty much just Oxygen and Nitrogen.
The largest layer of the Sun's atmosphere is the corona. It is the outermost layer, extending millions of kilometers into space. The corona is most easily seen during a total solar eclipse.
That depends on the weight and sise of the feather In a vacuum it would fall as fast as a canon ball. In the atmasphere friction through the air would slow it so sise and weight and shape comes into it.
Saturn's atmosphere is primarily composed of hydrogen and helium, with traces of methane, ammonia, and water vapor. These gases create the vibrant colors and bands seen on the planet's surface, due to the scattering and absorption of sunlight.
Planets change over time due to various factors such as volcanic activity, weathering, erosion, impacts from asteroids or comets, and internal processes like tectonic movements. These processes can alter a planet's surface, atmosphere, and composition, affecting its overall appearance and characteristics.
The Moon does not have a significant atmosphere like Earth does. Instead, it has an exosphere made up of very low-density gases. The lack of a substantial atmosphere is due to the Moon's weak gravitational force.
Our atmosphere helps in a number of ways: 1. It filters out harmful UV rays from the sun that would burn all living things. 2. It creates a blanket that keeps the temperature relatively stable. 3. The atmosphere provides oxygen needed to sustain animal life and carbon dioxide needed to sustain plant life. 4. It provides a mechanism for water to move from the oceans to land - allowing plants and animals to live on land. 5.it makes you feel sooooooooooooo much cuter
For a space ship to orbit the Earth it needs to be moving so fast sideways that as it falls towards the Earth the curvature of the Earth falls away below it. The higher the orbit the greater the sideways speed needs to be. Thus when the space ship wants to come back to the earth it is moving very very fast and when it hits the air in the atmosphere the fridtion with the air cause the spaceship to heat up. The process of heating up slows the ships speed - the energy of the speed is turned into heat.
